; 3D-system example. Use the following formulas to rotate a point:
;
; Rotate around x-axis
; Y = Y * COS(xang) - Z * SIN(xang) / 256
; Z = Y * SIN(xang) + Z * COS(xang) / 256
;
; Rotate around y-axis
; X = X * COS(yang) - Z * SIN(yang) / 256
; Z = X * SIN(yang) + Z * COS(yang) / 256
;
; Rotate around z-axis
; X = X * COS(zang) - Y * SIN(zang) / 256
; Y = X * SIN(zang) + Y * COS(zang) / 256
;
; Divide by 256 coz we have multiplyd our sin values with 256 too.
; This example isn't too fast right now but it'll work just fine.
